Would Endwalker have been better if we never visited Elpis at all?

And even after being said so by the dev team, people still reject it because they full heartily believe that the unsundered world was a better one.

What was said by the dev team? That Venat believed that this is "probably" what would happen to them "if they continued as they were"? You are speaking as though this statement is some damning, objective end to the matter but the fact remains that everything that was done to their society was done based on the subjective thought process of a single person. As stated by the devs. The devs even ask you to think about this person's right to make that decision for mankind; comparing it to another well-known antagonist's mindset in the game.

No one is making anything up or refusing to come to terms with it. They're pointing out the blatant contradictions and inconsistencies in the story and why it all falls apart with even the smallest bit of examination. The devs inability to be firm and decisive on any points also does not help the story in any way, with them making statements like

"Whatever you would be doing is what X would be doing"
"We *think* that's what would have happened"
"We'll allow you to come to your own conclusions about that"

In response to very pertinent lore questions.
Brilliant.
